Easy Operation with Maximum Benefits
The Eaton EZ intelligent relays provide
basic functions that users could only
implement previously with individually
installed and wired devices. The EZD
multi-function displays offer powerful
visualization functions.
The EZ intelligent relays bring timers,
relays, counters, analog functions, inputs
and outputs into one compact device that is
easily configured. The EZ family of products
provides exceptional levels of flexibility
together with substantial savings in
commissioning time and effort. Other terms often used for intelligent
relay are relay replacer, control relay and
smart relay.
The EZ intelligent relays are available in
more than 20 different styles that support
from 12 I/O up to 320 I/O points.

ApplicationsDesigned for use in automation for
commercial & industrial sectors, domestic and building controls
providing the ideal solution for lighting, energy
management, industrial control, watering,
pump control, HVAC and home automation.

Simplicity and User-Friendly Operation
Every rung or circuit connection is wired just
like you remember: Contact – Contact –
Contact Coil – Done! The devices allow the
"wiring" of 128 or 256 rungs of circuit
connections.

EZ-To-Use SoftwareThe EZSoft software is a user-friendly circuit diagram editor for the
EZ500/700/800 and EZD intelligent relays.
EZSoft includes an integrated offline simulation tool that allows
users to test the functionality of the circuit diagram before commissioning.
Simulate input switches, pushbuttons, and analog voltages. EZSoft even
includes an oscilloscope mode which allows you to capture input and output
waveforms in real time!

Security Means Safety
The finished circuit diagram is stored
internally and can also be saved externally
on a memory module (EEPROM) for
transport, security and backup. Multi-level
password protection secures your circuit
diagram from unauthorized viewing, editing,
copying or deleting.

Easy to useWe use these intelligent relays for various control systems in our laboratory. We use them for opening/closing valves in timed sequences and for interlocking vacuum equipment. Our control actions are based on time or inputs, and the output action is opening/closing valves. Inputs include manual switches and set-point relays. There is also an option for analog input.
The ladder logic software is relatively easy to learn, and there is a simulation mode that allows you to check the function of your code. The units are low cost and can replace more expensive control systems based on other PLCs or computer DAQ cards. The one thing that is missing is PID loops for temperature control.
We have 3 of them, and they work well. I would recommend this product if it meets your control needs.
